sequelize.js

问题 I am on Node 8 with Sequelize.js Gtting the following error when trying to use await . SyntaxError: await is only valid in async function Code: async function addEvent(req, callback) { var db = req.app.get('db'); var event = req.body.event db.App.findOne({ where: { owner_id: req.user_id, } }).then((app) => { let promise = new Promise((resolve, reject) => { setTimeout(() => resolve("done!"), 6000) }) // I get an error at this point let result = await promise; // let result = await promise; //

问题 I'm trying to save sequelize models with their associations. All the associations are one to one. Retrieving models with associations from the database works just fine but inserting them is another matter and the documentation is just making me more confused. Here's my insert method: models .radcheck .create(user, { include: [{model: models.skraningar}, {model: models.radusergroup}, {model: models.radippool}] }) .then(success, error); I've seen so many ways to do this both in the

问题 I have a User-table and a userAttributes table. Every user can only have one instance of each userAttribute, so I would like to create a composite unique index for the columns name and userId(That is created by userAttributes.belongsTo.) How can this be done? UserAttribute = sequelize.define('userAttributes', { name: { type: Sequelize.STRING, allowNull: false, unique: 'nameIndex', validate: { isIn: [['phone', 'name','driverRequest']], } }, value: { type: Sequelize.STRING, allowNull: false },

问题 I am trying to update my database using Sequelize migrations so I have tried to write a Sequelize migrations like this 'use strict'; module.exports = { up: (queryInterface, Sequelize, migration) => { queryInterface.addColumn('coaching_class_entries', 'bill_cycle', { type: Sequelize.INTEGER(4), allowNull: false, defaultValue: '0', field: 'bill_cycle', after: 'fees' }) .then(() => queryInterface.addColumn('coaching_classes', 'bill_plans', { type: Sequelize.JSON, allowNull: false, defaultValue:

问题 I've got Sequelize-based code that runs fine in a Node.js project. I moved that code into an AWS Lambda handler and am testing it with the node-lambda module. Now the Sequelize code seems to be skipped. I'm not sure if the promise isn't being handled before the Lambda finishes, or if I'm missing something else. The following code skips the "during" console.log as shown in the output below. var models = require('./models'); exports.handler = function( event, context, callback ) { console.log(

问题 Summary: I want to change the application name of the connection string when initialize a new sequalize object. based on this stackoverflow question, I set the appName of dialectOptions as follows: let conn = new Sequelize(this.models.sequelize.config.database, this.models.sequelize.config.username, this.models.sequelize.config.password, { host: this.models.sequelize.config.host, dialect: this.models.sequelize.getDialect(), dialectOptions: { appName: "userid=-2@gid=" + gid } }); Question:

问题 say I have two models: Post and Comment , now I can use Post.findAll() to get all posts, but I also need the comment count of each post, I can make a loop and use post.countComments() to get the count, but is it possible to do that in one query? thanks 回答1: You can do something like this: var attributes = Object.keys(Post.attributes); var sequelize = Post.sequelize; attributes.push([sequelize.literal('(SELECT COUNT(*) FROM "Comments" where "Comments"."postId" = "Post"."postId")'),

问题 I like to convert the following query into sequelize code select * from table_a inner join table_b on table_a.column_1 = table_b.column_1 and table_a.column_2 = table_b.column_2 I have tried many approaches and followed many provided solution but I am unable to achieve the desired query from sequelize code. The max I achieve is following : select * from table_a inner join table_b on table_a.column_1 = table_b.column_1 I want the second condition also. and table_a.column_2 = table_b.column_2

问题 I find the Sequelize docs are long and hard to understand if you are using tables that don't follow their conventions. If I have two tables: people ( people_id - uuid name - text ) parties ( parties_id - uuid people_id - uuid (foreign key) ) Am I right to define my models like this? function getPeople() { let entity = {}; entity['people_id'] = {type: Sequelize.UUID, primaryKey: true, allowNull : false}; entity['name'] = Sequelize.TEXT; return sequelize.define('dbo.people', entity, options); }

问题 I followed this tutorial from scotch.io on how to build user authentication using node.js (great tutorial by the way). However, when verifyPassword(password) is called to check user password, the value is always returned as false for some reason. I'm using brcypt.js and sequelize.js for my express project. custom methods for model User: classMethods : { setPassword : function(password) { return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null); } }, instanceMethods: { verifyPassword:
